Yet another "Do I have enough truck?"

op wrote:
I posted up my numbers, Trailer 5,100 dry weight 7,500 GVWR (unknown pin weight) Truck GVWR 10,000, GAWR FRT 4,100, GAWR RR 7,500, 10,000 trailer 5th wheel or WDH. I cannot find a CGVWR for the 97 C3500 as equiped. If the GVWR of 10,000 on the door sticker is in fact the CGVWR then 7,500 max trailer is to big because I weigh over 250 and the 35 gallons of fuel weighs 210 the hitch has weight, so 7500 trailer 500 for me the fuel and hitch only leaves 2,000 for the truck. I need to get the truck fueled and get the family in it and get to the scales. Do I get 10,000 GVWR for the truck and I can tow 10,000 for a combine total of 20,000 GVW as I interpret the information I have.

Trucks do not have a GCWR number stickerd nor is it a requirement to have one.

Some truck facts from your numbers.
'97 3500 DRW GM truck with a 454 big block
has a 10000 lb GVWR
has a 4100 FAWR
has a 7500 RAWR
tow ratings run up to 10000 lbs
These numbers are all you need.

I have a '98 3500 DRW 454 crew cab 4x4 4.10 gears with a 10000 lb tow rating. I use this truck custom hauling cattle/horses pasture to pasture or to sales barns with a 15.5k GN tri axle (7k axles)stock trailer.

This trucks rear axle weighs 3040 lb which leaves 4400 lbs for a payload. As I mentioned trucks don't carry a gross combined weight rating (GCWR) however a 10k tow rating and a 10k GVWR can give you a 20k GCWR.
When you scale the truck keep a copy of separate front and rear axle weights in the glove box. A single gross weight with no axle weight numbers is worthless number for a truck towing a trailer.
